Smart battery storage brAIn is now also in Prešov: Cold storages are switching to green energy

Another specially modified and customized brAIn battery storage by FUERGY is now up and running. With a capacity of 216 kWh when combined with solar panels, the system was installed in the MRAZIARNE SERVIS spol. s r.o. refrigeration company at no cost to the company. The entire project was financed by Slovenské elektrárne - energetické služby, the energy supplier, through the Energy as a Service program.

The food industry is well-known to be extreme users of energy and with an annual electricity consumption of about 2,000 MWh, MRAZIARNE SERVIS is no exception. The company therefore decided to optimize consumption by including a local source for energy production. By generating its own green energy through rooftop solar panels, with an installed capacity of 400 kWp, the company is now able to cover nearly one-fifth of its total needs.

In addition to the solar panels, we have installed a customized 216 kWh brAIn smart battery storage system, which shifts the production and consumption of electricity over time and maximizes the use of their solar system. You can read more about how the brAIn smart battery storage works in our blog article A guide to the brAIn high-capacity smart battery storage brAIn by FUERGY.

As a bonus, here is a short video of the installation:

Simply put, the system charges and discharges batteries automatically and continuously throughout the day in such a way that each cycle maximizes financial earnings. In other words, the brAIn does more than just store excess solar energy or off-peak electricity, the integrated FUERGY software makes much more sophisticated decisions based on a range of internal and external data. For example, on weekends when the company is closed, the system will decide whether it is more financially advantageous to charge batteries with solar energy or surplus electricity from the power grid.

By providing non-certified ancillary services which also help to maintain the stability of the power grid, the brAIn efficiently replaces traditional fossil-fuel energy providers in an emission-free manner, contributing to an overall reduction of CO2 emissions. The amount of CO2 emissions saved can be disclosed in MRAZIARNE SERVIS’s ESG report, i.e. a report on the company’s Environmental, Social and corporate Governance data.

Green technologies without investment costs

The way our software manages the process of charging and discharging batteries allows the storage system to gradually pay for itself, which is also interesting from an investor's perspective.

This is how MRAZIARNE SERVIS received the solar panels and brAIn battery storage for free. Both green technologies were financed by Slovenské elektrárne - energetické služby, which is also MRAZIARNE SERVIS’s electricity supplier, as part of the Energy as a Service model.

Energy as a Service is a revolutionary approach that facilitates access to modern green technologies for companies that cannot afford such investment but want to be greener, more energy self-sufficient and more sustainable.

Today, MRAZIARNE SERVIS not only produces its own green energy but also gains a share of the total profit gained through its smart battery management. What is more, their share will increase after the end of the contract.

Backup power functionality

In addition to overall lower electricity costs, MRAZIARNE SERVIS did not have to struggle with project preparation, approvals and all the paperwork that comes with the installation of green technologies. Everything was handled by FUERGY and Slovenské elektrárne - energetické služby.

MRAZIARNE SERVIS has a stable electricity consumption pattern and it is not critically dependent on uninterrupted operation. Therefore there was no need to allocate part of capacity to provide backup power or UPS functionality.

Dedicating part of the capacity means that a portion of the battery storage remains fully charged, untouched by the software, which translates into a slightly lower financial gains able to be achieved through smart energy management. However, each brAIn does guarantee the coverage of micro power outages should they occur within the discharge cycle.

Interior of 216 kWh smart battery storage brAIn

MRAZIARNE SERVIS has also gained 100% tolerance for deviations. This means that the company need not worry about fluctuations in electricity production or consumption, or any penalties for failing to meet its energy plans. It is not even necessary to prepare these plans anymore as all electricity production and consumption plans are automatically generated by the FUERGY software and forwarded directly to the energy supplier.

What made the installation specific?

Every building has its own specifics and sometimes it can be a bit more complicated to install battery storage on site. Any modifications to the installation site or terrain can affect the overall return on investment and could extend delivery time by several weeks. A site inspection is, therefore, an essential part of each brAIn project.

If possible, we install battery storage close to the main switchboard. Since there was not enough space for an interior version of the brAIn system, which does not require a protective outdoor case and therefore also has a better return on investment, we chose a 10-foot container exterior version.

Custom-built metal platform for exterior installation in a flood zone

As the building is located in a flood zone, the storage also needed to be raised to a height of 1.5 meters from the ground, which was solved by constructing a metal platform set into a concrete base.

Despite these custom modifications, the brAIn’s payback period remains highly attractive.

Planned extensions and trouble-free maintenance

Capacity-wise, the battery storage system will improve with a future upgrade – flexibility brAIn for freezers and compressors. In total, the software will operate with a regulation power of around 300 kW, further increasing the overall financial gains from smart energy management.

Last but not least, MRAZIARNE SERVIS does not have to worry about a single thing. Maintenance of the green technologies and any repairs are covered by FUERGY and the electricity supplier. They are free to simply enjoy their new sustainable solutions.
